The high hardness of alumina ceramics allows it to be used to make knives, grinding wheels, abrasives, drawing dies, extrusion dies, bearings, etc. It also has the characteristics of high melting point and good corrosion resistance. It is also necessary for the production of furnace tubes, crucibles, fibers, thermocouple protection tubes and other materials. In addition, alumina ceramics can also be made into pure metal and single crystal growth crucibles, human joints, artificial bones, sodium vapor lamps, microwave fairings, infrared windows, laser oscillation components, solar cell materials and battery materials.
Wear Resistant Alumina Ceramic Beads
My factory looking for distributors.
Features:
1. The wear-resistant alumina ceramic beaded bone-shaped 2-hole porcelain beads can realize the temperature measurement requirements of turning, turning and twisting under thermocouple complicated conditions.
2. With different length and diameter,2 bores ceramic beads and oval knobs could satisfy any assembly requirement.
Product information
